Users can view all the customized route templates in the template menu, slip from right to left on a template and you can choose to detele it. 2. Capturing waypoints In Waypoints mode, click to capture the aircraft attitude (including longitude, latitude, height and nose pointing direction) properties to build a new waypoint during flight. This function is always available when the UAV is hovering or flying.
3. GPS SNR Display iPad Ground Station ha s added “SNR Health” and “SNR Fluctuation” index monitors for GPS sig nals. Pilots will be able to monitor GPS signal quality, ensuring they have strong and stable signals for better flight performance. By referring to these two values, pilots will be empowered to find the best locations for takeoff and flight, while also detecting areas that might interfere with GPS signals. Click . The SNR interface provides you with “SNR Health” and “SNR Fluctuation” index monitors whose values change according to aircraft maneuvers and environmental interference.

 The “SNR Health Index” shows the GPS signal strength captured by the GPS receiver. A larger number indicates a stronger GPS signal. We highly recommend pilots only take off when the SNR health value is greater than 36.© 201 3- 201 5 DJI. All Rights Reserved. 

### - 6 -

 The “SNR Fluctuation Index” shows the overall stability of the craft’s current GPS signal. A smaller number means that the signals will fluctuate less and provide a more stable GPS signal overall.



# 2 .4 Flight Limit of Special Areas All UAV operators should abide by all regulations from such organizations at ICAO (International Civil Aviation Organization) and per country airspace regulations. For safety reasons, key areas have been restricted, such as: a) Within the radius of 8Km from the airport. Users will not be able to build waypoints or Home points in designated special areas and the waypoint routines go through these special areas are invalid , and the UAV will fail to cruise to those areas. All the special areas have been restricted are specified on the DJI official website and please refer to Special Areas List ( http://www.dji.com/fly-safe/category- gs ) to obtain details.© 201 3- 201 5 DJI.
